Ok, will replace with "start", since only strings are used for commands. Usually context menus on file managers include two items: "Open" that opens immediately "Open With" with a list of commands So "start" will be used for "Open With" if someone prefers this. Then a new command 'dired-do-open' bound to the "Open" menu item will hard-code 'w32-shell-execute' call with the "open" command.

It doesn't call them by default.

Ok, then let's add this to dired-aux.el since it's used in dired.

Ok, I removed mailcap and xdg from defaults:

IMO, read-shell-command should not by default call these helpers.
If we cannot find a suitable non-preloaded file to put this stuff (is
subr-x.el okay, for example?), it's okay to start a new file.

That's immaterial: M-n is an integral part of shell-command (of any
command, really), and thus should not cause such massive loading of
helper stuff, not by default anyway. Why do we think we can
second-guess what user wants from shell-command guessing? why do we
think the user will want XDG in this picture? or mailcap? These are
explicit user preferences, and we should leave it to the users to
express their preferences.

Likewise here: users should by default be able to invoke these Dired
commands without automatically loading those helpers, which come with
quite tangible ballast. For Dired, this is perhaps less important,
since Dired itself is an optional package, but still: I think it's
wrong to do this by default.

I can't find other place to put these 50 lines. I added to simple.el
near read-shell-command because it's used by read-shell-command.
If you want this could be moved to dired-aux.el and placed
near dired-guess-shell-command. But would it be quite inappropriate
since shell-command-guess is a more general feature?
> And let's try to implement this in a way that won't load mailcap, xdg,

It already doesn't load mailcap, xdg, dired, and dired-aux
when shell-command is invoked. It loads these files only
when the user needs to use them and types 'M-n' twice in the
minibuffer of read-shell-command ('M-!' and 'M-&').
Also shell-command-guess is used by dired-read-shell-command
('!' and '&' on a file in dired).

To add minimal complexity we could use as an example the recent design of context-menu-functions that is a hook. Then we could create a new customizable hook that can contain a list of functions that return the command candidates depending on the argument with file names. Then its possible options for such hook could include: - xdg-open-function - mailcap-function that adds mailcap candidates - dired-x-guess that adds existing dired-guess-shell-alist-default - Windows-specific candidates from w32-shell-execute - etc.

Yes, but the added complexity should be small, and I think we cannot do without that: tools like xdg-open will never be able to satisfy all the needs of Emacs users, because Emacs is not just a file manager capable of starting applications.

Helm is using an alist to store (command . extension), if no command is found, it uses mailcap to find a default unless the user specify a new association interactively (prefix arg), user can add arguments to the command if needed, before or after the filename(s) arguments. In addition, on GNU/Linux it is possible to detach the process from Emacs. See helm-external.el, I am working on it currently. -- Thierry

Mostly, I am afraid that a suggestion which satisfies everyone in terms of functionality will simply pile on more features to Emacs, in an area which is already too complicated. I don't see why launching external applications can't be left to the operating environment, as all environments now have mature systems for doing this. If someone such as you wants more complex functionality, that can be served by a third-party package; it doesn't need to be built in to Emacs. -- https://rrt.sc3d.org --000000000000e3e39d05cf0b51a7 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable <div dir=3D"ltr"><div class=3D"gmail_quote"><div dir=3D"ltr" class=3D"gmail= _attr">On Sat, 23 Oct 2021 at 16:45, Stefan Kangas <<a href=3D"mailto:st= efan@HIDDEN">stefan@HIDDEN</a>> wrote:<br></div><blockquote clas= s=3D"gmail_quote" style=3D"margin:0 0 0 .8ex;border-left:1px #ccc solid;pad= ding-left:1ex"><br> What I want is more or less the exact behavior of xdg-open, but I want<br> to be able to check the actual command (e.g. "evince", not just<b= r> "xdg-open") before pressing RET.<br></blockquote><div><br></div><= div><div style=3D"font-family:arial,helvetica,sans-serif;font-size:small" c= lass=3D"gmail_default">I don't understand why this is useful.

Such a command is long overdue. I used the following command
for a long time, and forgot it's not in dired-x. I don't suggest
to use this implementation, but something like this. Then like
clicking the right mouse button on a file shows a list of
available apps to open the file in, and M-& does practically the same
with the keyboard. Then like double clicking on an icon,
some key should use the default command to open the file.

Such a command has been written many times and people add it to their local configs. I have it bound on X in dired and use it far more often than I do M-!. Such a command emulates what double clicking on an icon does which most of the time is what a user wants (because it's configured it do what their most common app need is). Having emacs provide the command means it could be correct reguarding shell quoting and other small issues that people might get wrong on their own. For those that want more control either in picking the command that is run or seeing it beforehand, they can use and configure dired-guess-shell-alist-default. -- Howard

What I want is more or less the exact behavior of xdg-open, but I want to be able to check the actual command (e.g. "evince", not just "xdg-open") before pressing RET. I also want to be able to override xdg-open with customizations inside Emacs. > I agree with Eli's reasoning. Please bare with me as I'm trying to understand. Is your preference still to just run "xdg-open", as you explained in your original bug report? (It was quite some time ago, which is why I'm asking, in case your position has changed.) Do you agree that if we could get my idea to work, you could have your cake and eat it too? IOW, do you disagree with the approach because you think it is infeasible to make it work well, or because you don't think that the feature sounds useful? Or do you merely disagree with using mailcap to implement it? Thanks.

I don't see that shooting away blindly to xdg-open is satisfactory; the
user should be able to a) know which command is being run before running
it and b) modify it on the fly. Maybe I want to open PDF:s first with
one and then another PDF reader to see if it looks the same, just as I
would be able to from a graphical file manager.
Thus, the most important question to my mind is "how can we get the
default command for a file in the best way".
I think ideally we should get this from the system, optionally with
overrides and/or fallbacks from Emacs or the user. I don't particularly
care if it comes from mailcap, from /usr/share/applications, but we
should preferably pick the "best" one.
Eli says that portability is a concern with mailcap, which is true but
also not something we can't work around.
You say that mailcap is the wrong tool for the job. (Why?)
I claim that the `xdg-open' script does not seem to solve the problem.
Then I ask: what is the correct tool for the job of finding the command
to run?
Maybe we need try several different things? I see that `xdg-open' tries
all kinds of different things ("gio open", "gvfs open", "open_generic",
etc.). But our needs are different: we want the command as a string, we
don't just want to run it.
PS. For the sake of simplicity, I would suggest that we could first
figure out what to do on GNU/Linux and then we'll see if we can get
that solution to work elsewhere or if we need to get other things in
place.

Not sure it will help. Example: $ file --mime-type -k -b lisp/international/uni-bidi.el application/octet-stream Looks like there are some fundamental problems in 'file' that make it not ideal for this purpose, to say the least. Which, to me, just reiterates what I already said up-thread: we should allow users to override what the system-level tools provide, because they will never be 100% satisfactory for our needs.

Isn't that just "file --mime-type -b"? file is a BSD command AFAICT so it should presumably be available almost everywhere. I also see in the man page than a certain Reuben Thomas has been involved in its development so maybe he has something to add here. :-)

I think that's a separate issue: how to deal with a failure to invoke
the program which we guessed would be appropriate for the file in
question. I could argue that we should try invoking the program
anyway, because failure to invoke it could mean the user should
install some component, and that is useful information for the user.

Here, the above returns something much less useful:
("pdftotext ? -" "gv -safer")
None of that would have helped me to view a PDF file.
So if we want to use mailcap for this, we'd need to extend that, and
make it smarter, in particular on non-GNU/Linux platforms.
More generally, I'm not sure mailcap is the right tool for the job:
its main purpose is to view attachments to email messages, where we
generally have metadata (MIME etc.) which is not necessarily available
for arbitrary disk files.

That sounds like exactly the right thing to do. So we need to add stuff
here, without taking anything away.
However, I will add that while we maintain our current capabilities for
customization, we might want to consider removing or updating some
entries from `dired-guess-shell-alist-default'. For example, we
currently recommend xpdf for PDF:s, which, sure, is presumably available
"everywhere", but also is pretty lacking in features and just plain
clunky compared to something like evince.
To make matters even worse,
emacs -Q --eval "(progn (require 'dired-x) (dired \"~\"))"
happily offers up xpdf as the default command for PDF:s even though I
don't even have xpdf installed! So perhaps it's not that ubiquitous
these days... you have to specifically install it to even have it.
Looking even more closely at this, I guess `xdg-open' could be used as
some final fallback, but it doesn't seem to add anything that isn't
already available from mailcap? And we already have
`mailcap-file-default-commands', so why not just provide a default based
on that?
On my machine, I get the very reasonable:
(mailcap-file-default-commands '("foo.pdf"))
=> ("evince" "xdg-open")
So why not just move the guessing stuff over to dired.el, re-base it on
mailcap, and minimize the list in `dired-guess-shell-alist-default' to
something more reasonable. Perhaps that list could be just nil by
default if we have the usual mailcap stuff?

Emacs's ability to run programs given a file can extend and surpass those of the underlying OS, and the ability of Emacs users to configure and customize that in a unified system-independent manner are either better or simply not available at all in the OS-level tools which offer similar functionality. So I think it would be nice to extend dired-guess-shell-* so that it could delegate to the OS-level capabilities like xdg-open or w32-shell-execute, but we should preserve the abilities to override or extend that with Emacs-level associations between files and programs. > > 2.

I'm not sure I understand what exactly is proposed here as "step 1", but it sounds like it's the same as my "extend dired-guess-shell-*" proposal above? Then I agree, of course, I just think that we don't need to do anything else, and in particular we should never remove the ability of Emacs users to augment/extend/override those system-level facilities.

I agree, but I will add that it would be very nice if we don't lose the capability of seeing which command will be run on a file when typing & (dired-do-async-shell-command) on a file in Dired. It sucks when the default only says "xdg-open", as you don't know what program that will open or if it is indeed the one you want. Does xdg-open have the capability to just print what it would run without actually executing it? I can't see such a flag on Debian stable/bookworm. If that is missing, should we perhaps add a feature request for it? https://www.freedesktop.org/wiki/Software/xdg-utils/ But in that case, we would need to check for that capability first, somehow... > 2.

run-mailcap always runs the first alternative, but with
`mailcap-file-default-commands' you can select a command
to run using several M-n.

Instead of customization, a more useful UI would be to remember
the most frequently used commands, and provide them at the top
of the completions in the minibuffer.

Yes, this is so when the prompt displays the default value.

It would be good to discourage customization of
dired-guess-shell-alist-{default,user}, and steer users towards the
non-program-specific mechanisms. It would also be good eventually not to
have to maintain the list, or indeed the dired-guess-shell mechanism at all.
As for your mention of "the first M-n", as far as I can discover, the first
time I press M-n, the default command, which was already mentioned in the
prompt, is simply inserted at point, as if I had typed it. So is "the first
suggestion that the user will get after the first M-n" actually the same
thing as "the default suggestion"? (I hope so!)

We could leave the original list intact, and add xdg-open/w32-shell-execute
to the top of the list, so it would be the first suggestion that the user
will get after the first M-n.
There is a good example how to check its availability in
`browse-url-can-use-xdg-open' that could be moved

So, yes, both of these commands can be added. My original point is that they're not currently used; instead there is a custom list that has to be configured separately by the user from either of these. Hence, I suggest using these commands (and similarly "open" on Mac OS, and, as per Eli's suggestion, w32-shell-execute on Windows) instead of the current contents of dired-guess-shell-alist-default. Since each of these commands tackles all file types, it would seem simplest to add a new function shell-execute, modelled on w32-shell-execute, and have dired-read-shell-command use that instead of dired-guess-shell-command, which could then become an option that shell-execute can be configured to use, for those who are used to it. -- http://rrt.sc3d.org --001a11c35704e0bead04ff658ef6 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: quoted-printable <div dir=3D"ltr"><div class=3D"gmail_extra"><div class=3D"gmail_quote">On 3= 0 July 2014 00:49, Juri Linkov <span dir=3D"ltr"><<a href=3D"mailto:juri= @jurta.org" target=3D"_blank">juri@HIDDEN</a>></span> wrote:<br><bloc= kquote class=3D"gmail_quote" style=3D"margin:0 0 0 .8ex;border-left:1px #cc= c solid;padding-left:1ex"> > These days, there are mature programs for launching an arbitrary file = with<br> > an appropriate viewer: run-mailcap (which is mature to the point of<br= > > obsolescence) and<br> <br> run-mailcap is fully supported by shell-command and async-shell-command whe= re<br> the list of available commands can be accessed using M-n in its minibuffer.= <br></blockquote><div><br></div><div>I can't see any mention of run-mai= lcap in the Emacs source; do you mean simply that it's possible to add = it to the list of commands used?<br> </div><div>=C2=A0</div><blockquote class=3D"gmail_quote" style=3D"margin:0 = 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> > xdg-open on GNU systems; open on Mac OS X; start on MS Windows).<br> <br> xdg-open is a single command that is too easy to add to the top of this lis= t.<br> </blockquote></div><br></div><div class=3D"gmail_extra">Did you mean "= easy too"?<br><br></div><div class=3D"gmail_extra">So, yes, both of th= ese commands can be added.<br><br>My original point is that they're not= currently used; instead there is a custom list that has to be configured s= eparately by the user from either of these.<br> <br>Hence, I suggest using these commands (and similarly "open" o= n Mac OS, and, as per Eli's suggestion, w32-shell-execute on Windows) i= nstead of the current contents of dired-guess-shell-alist-default.<br><br> </div><div class=3D"gmail_extra">Since each of these commands tackles all f= ile types, it would seem simplest to add a new function shell-execute, mode= lled on w32-shell-execute, and have dired-read-shell-command use that inste= ad of dired-guess-shell-command, which could then become an option that she= ll-execute can be configured to use, for those who are used to it.<br> </div><div class=3D"gmail_extra"><br>-- <br><a href=3D"http://rrt.sc3d.org"= >http://rrt.sc3d.org</a> </div></div> --001a11c35704e0bead04ff658ef6--

It would be a bad idea to use 'start' on Windows: it has too many quirks regarding quoting of its command line. Instead, just invoke the existing primitive w32-shell-execute with the 'open' verb. As a nice side effect, this will support Unicode file names, something that is currently impossible when you invoke an external command.

xdg-open is a single command that is too easy to add to the top of this list.

These days, there are mature programs for launching an arbitrary file with
an appropriate viewer: run-mailcap (which is mature to the point of
obsolescence) and xdg-open on GNU systems; open on Mac OS X; start on MS
Windows).
xdg-open already works reasonably well:
http://lists.gnu.org/archive/html/help-gnu-emacs/2012-01/msg00143.html
(I have a fix for the "multiple files" problem, which I'll be sending to
xdg-utils upstream when I can.)
Hence it would seem sensible to have a new default for
dired-guess-shell-alist-default, which matches any file and returns the
appropriate command for the OS, probably doing some testing to see which
commands are available on a GNU system ("xdg-open", "gvfs-open", "see"=E2=
=80=A6).
The user then only needs to understand and configure one command-launching
system, and the coverage of different filetypes is much more comprehensive
in most such systems than in dired-x.el.
An advantage to Emacs is that this system could then be used elsewhere. For
example, org-mode already has a similar, separate system, org-file-apps,
which might benefit from building on dired-x, and only retaining its own
configuration where it's desirable to open a file "internally" to org-mode.
